from bug 384975 Steps to reproduce bug: Turn on global menu. Turn on Akregator Select any feed in Akregator Boom - Crash
I'm not sure if it's relevant for this bug but it is for sure relevant to bug 384975 marked as duplicate. The problem is that akregator kpart is initialized twice, recursively. (See attached trace #45 and #5) Akregator::MainWindow::loadPart() is called twice. Because of that in ActionManagerImpl we have corrupted reference to d->actionCollection that causes dump on calling setArticleActionsEnabled. The reason of recursive initialization seams to be method Akregator::MainWindow::saveProperties() that is called by QtWebEngine before kpart if fully initialized. The simplest solution would be to remove initialization of kpart from this method and returning if kpart it's not initialized. Or skipping initialization only in such case if possible.
Created attachment 110492 [details] Trace of double initialisation
Created attachment 110493 [details] The simplest fix
I saw at least one report by a tester saying that even with this patch feeds still get corrupted sometime.
This fix do not prevent from corrupting feeds. In my case it was happening sometimes after akregator crash. It only make akregator usable with global menu. it avoids akregator crashing 100% times. After applying this patch, I didn't have any crash.

After applying this patch, I didn't have any crash. I can confirm this patch fixes akregator crash with global menu enabled.

I'm not original reported but I think I used to see this bug too. I don't see it now (at least on Plasma Wayland).
